(function of navigational system)
The IGN switch of corresponding vehicle or the ACC switch is switched to ON or corresponding guider 200 from OFF switch are when OFF is switched to ON, and the expression track search requires the index i of number of times to be reset to " 0 " (Fig. 2/step 202).
In addition, in guider 200, first arithmetic processing section 210 is based on the gps signal that is received by communicator etc., and shape constancy is measured user's position p (t).And, utilize input media 201 input destination locations p the user 2(i) time, by 210 pairs of these destination locations of first arithmetic processing section p 2(i) be familiar with.
Then, first arithmetic processing section 210 judges that track search this time from the user of whether passing through input media 201 requires (Fig. 2/step 204).(Fig. 2/step 204 when judgement has the track search requirement ... be), index i then increases " 1 " (Fig. 2/step 206).
In addition, first arithmetic processing section 210 is at from ti customer location p constantly 0(i) to destination locations p 2(i) explore the first guidance path r that is used to guide this user 1(i) (Fig. 2/step 210).Therefore, shown in the line of the single-point among Fig. 3 (a), output shows the position p that links the user on output unit 202 0(i) and destination locations p 2(i) the first guidance path r 1(i).
And, by first arithmetic processing section, 210 navigation servers, 100 transmission users' position p 0(i) and destination locations p 2(i) in addition, also be included in the first guidance path r with having to these navigation server 100 transmissions 1(i) the one or more centre positions in require Req (i) (Fig. 2/arrow X1).In requiring Req (i), be useful on the guider identifying information of navigation by recognition device 200 or be used to discern user's the customer identification information except apposition, also apposition index i.
In addition, also can omit the first guidance path r 1(i) (Fig. 2/step 210) handled in exploration, but 100 transmissions of navigation server are not included in the described first guidance path r with having 1(i) centre position in require Req (i).The output signal etc. that can locate or carry the vehicle speed sensor on vehicle according to the user's who is measured by guider 200 sequential determines the user or whether vehicle is moving, and judges whether to explore the first guidance path r 1(i).
In navigation server 100, by first support arithmetic processing section 110 as requested Req (i) judge whether index i is 1 (Fig. 2/step 102).This judgement be equivalent to judge in this user is during same moving (from the IGN switch of vehicle etc. be switched to ON play till being switched to OFF during etc.) whether the exploration resume of support path R (i) arranged.
Judging that index i is 1 o'clock (Fig. 2/step 102 ... be), be used for the user from its position p by 110 explorations of first arithmetic processing section 1(i) guide to destination locations p via the centre position 2(i) support path R (i) (Fig. 2/step 111).
Like this, shown in dotted line among Fig. 3 (a), explore from the first guidance path r 1(i) be included in the customer location p that requires among the Req (i) equally 0(i) to destination locations p 2(i) the support path R (i) till.Wherein, according to arriving destination locations p 2(i) the shortest or forecasting institute of displacement takes time the shortest or drives to destination locations p 2Condition such as the vehicle burnup is minimum (i) is explored described support path R (i).
(Fig. 2/step 102 when judging that index i is not 1 (being the numerical value more than 2) ...), further judgement does not this time require destination locations p this time going along with among the Req (i) 2(i) whether with last time required last time destination locations p going along with among the Req (i-1) 2(i-1) identical (Fig. 2/step 104).
When this result of determination be negate as a result the time (Fig. 2/step 104 ...), do not explore as hereinbefore from customer location p 0(i) to destination locations p 2(i) support path R (i) (Fig. 2/step 111).
On the other hand, (Fig. 2/step 104 when this result of determination is definite results ... be), by 110 couples of users' of the first support arithmetic processing section position p 0(i) situation of Zhou Bian the mobile form that might influence this user is familiar with (Fig. 2/step 106).
In this situation, include the mobile required time of prediction on the road that the user that recognizes moving from first Traffic Information or second Traffic Information, have or not traffic jam or its degree, have or not road traffic conditions such as traffic hazard.In addition, include in this situation weather, temperature, humidity, rainfall amount on the road that the user that recognizes according to weather information moving, have or not accumulated snow or road surface meteorological condition such as to freeze.
On this basis, support arithmetic processing section 110 based on described recognition results by first, customer location p will be from require Req (i) going along with 0(i) leave distance to a declared goal d 0(i) site setting more than becomes this time to support the starting point p of guidance path R (i) 1(i) (Fig. 2/step 108).
Distance to a declared goal d 0(i) be configured to following a kind of numerical value: the numerical value in the device 200 that navigates certainly sends during time lag (designated duration) till requiring Req (i) to play guidance path r (i) that the exploration result based on supporting path R (i) as described later obtains to be output more than user's the prediction displacement in guider 200.For example, can set described prediction displacement than modes such as length, set this prediction displacement according to recognition results maneuverability so that near the mobile required time of prediction that the road in the user moves (and customer location) located is short.
Like this, shown in Fig. 3 (b), last time support on the path R (i-1) (dotted line), from customer location p 0(i) leave distance to a declared goal d 0(i) above place apart from d (i) is configured to starting point p 1(i).
Then, supporting arithmetic processing section 110 explorations by first is used for the user from starting point (having passed through the user's of described time lag predicted position) p 1(i) guide to destination locations p 2(i) support guidance path R (i) (Fig. 2/step 112).Therefore, shown in solid line among Fig. 3 (b), explore from having passed through the user in predicting position p of time lag 1(i) to destination locations p 2(i) support path R (i).
Then, support arithmetic processing section 120 by second and send highway section identifying information (Fig. 2/arrow X2) to the guider 200 that recognizes by the guider identifying information.This highway section identifying information is used for discerning at least a portion highway section that is included in a plurality of highway sections of supporting path R (i).
In guider 200, explore the second guidance path r by second arithmetic processing section 220 2(i) (Fig. 2/step 220).This second guidance path r 2(i) be used for the user is guided to destination locations p 2(i) and contain the highway section that with good grounds above-mentioned highway section identifying information is recognized.
Like this, shown in double dot dash line among Fig. 3 (b), output shows the predicted position p that links the user on output unit 202 1(i) and destination locations p 2(i) the second guidance path r 2(i).In addition, the p that locates that links the user 0(i) and destination locations p 2(i) the second guidance path r 2(i) also can be output and be presented on the output unit 202.
(effect of navigational system)
According to the navigational system that can bring into play above-mentioned functions, the corresponding user's of having going along with who sends from guider 200 position p 0(i) and destination locations p 2(i) require Req (i) (i=1), explore by navigation server 100 and be used for the user is guided to this destination locations p 2(i) support path R (i) (with reference to Fig. 2/step 111 and Fig. 3 (a)).And,, explore the second guidance path r by guider 200 according to the highway section that comprises in the support path as the exploration result of this support path R (i) 2(i), and with its output (with reference to Fig. 2/step 220).Therefore, the user can be with according to this guidance path r 2(i) form that guided by guider 200 moves.
After this, sending from guider 200 with having and destination locations p last time 2(i-1) identical destination locations p this time 2(i) this time require Req (i) (i＞1) time, position p will be on last time supporting path R (i-1), require user going along with the Req (i) from this 0(i) leave the above place p of distance to a declared goal 1(i) set starting point for, explore and this time support path R (i) (with reference to Fig. 2/step 112 and Fig. 3 (b)).As previously mentioned, distance to a declared goal d 0(i) be configured to following a kind of numerical value: send at the device 200 navigation servers 100 that navigate certainly and require Req (i) to play 200 pairs of guiders should to require Req (i) to explore this guidance path r (i) and with the numerical value more than user's the prediction displacement in (time lag) during till its output.
Like this, the guider 200 corresponding second guidance path r that this time require to export this 2(i) time, the described second guidance path r this time 2(i) then from the user at the position in above-mentioned moment p 0Or than the more close destination locations p in this position 2(i) place begins.Particularly work as the user according to guidance path r (i-1) (the first guidance path r last time 1(i-1) or the second guidance path r last time 2(i-1)) when mobile, this second guidance path r 2(i) then begin from the path that the user is moving.Wherein, described guidance path r (i-1) is according to being set based on last time the exploration result who requires the support path R (i-1) that Req (i-1) explores.
So the user can not be forced to return, carry out significantly route change etc., but can be according to this second guidance path r 2(i) successfully move.Therefore, can be in view of user's position p 0(i) realize this time requiring guidance path (the second guidance path r particularly of Req (i) corresponding 2The raising of value (i)).
